FRANK C. W. KUEHN, OF HURON, SOUTH DAKOTA.

SASH-CORD FASTENER.

To all whom it may concern:

Be it known that I, FRANK C. W. KUEHN, a citizen of the United States,residing at Huron, in the county of Beadle and State of South Dakota,have invented certain new and useful Improvements in Sash CordFasteners; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This application is a division of my pending application, Serial No.519,049, filed September 22, 1909, for sash cord guide.

The object of the present invention is to provide an improved means foradjustably fastening the sash cord to the sash.

The patentable features of the pulley casing are covered in my priorapplication referred to above.

The invention consists in the features of construction and combinationsof parts hereinafter described and specified in the claims.

The accompanying drawing: Figure 1 is a front view of a window frameprovided with my sash balance, the top and parts of the sides of theframe being broken away to disclose the pulley casings and sash cords,and Fig. 2 is an enlarged broken section on the line g y of Fig. 1.

Referring more particularly to the drawing, 1 designates the windowframe and 2 and 3 the lower and upper sashes, respectively. As is usualin this class of sash balances, each of the sash cords 4 is secured atone end to the upper sash and at the other end to the lower sash, saidcords passing over pulleys arranged in casings 6 on the top of thewindow frame.

The upper portion of each lateral edge of.

the lower sash is grooved, as at 10, Fig. 3, to house one end of each ofthe sash cords. A fine cord 11, preferably of wire, is fastened aroundthe end of the sash cord by giving it one or more half hitches, as at12, or in any other suitable manner. This wire cord or flexibleconnection is fastened at its other end to a plain bolt 13 by having itsextremity passed through an opening 14 bored crosswise through saidbolt. Said flexible connection is made about two inches longerSpecification of Letters Patent.

than is necessary to reach down to the bolt so that when tightened itlies in several coils around the bolt. In winding the wire cord on thebolt, the coils of the former are directed toward the outside of thesash whereby, after a few turns of the bolt, said coils will commence tobind against the wall of the groove 10. The greater weight placed uponthe cord will then only cause it to bind more firmly.

The head 15 of the bolt is arranged on the outside of the sash whereaccess may be readily had to it for adjusting the cord. In order not tocome in contact with the frame, the bolt is arranged out of the way ofthe window stop. It will be understood that by turning the bolts one wayor the other, the sash cords may be loosened or tightened, as requiredto cause the sashes to fit accurately in the frame.

I claim:

1. The combination, with the lower sash having a groove in its edge, anda sash cord extending into said groove, of a bolt ex tending across saidgroove, and means of connection between said bolt and sash cord wherebythe latter may be adjusted with respect to the sash by rotating saidbolt.

2. The combination, with the lower sash having a groove in its edge, anda sash cord extending into said groove, of a bolt extending across saidgroove with its head arranged on the front face of the sash, and meansof connection between said bolt and sash cord whereby the latter may bead justed with respect to the sash by rotating said bolt.

3. The combination, with the lower sash having a groove in its edge, anda sash cord extending into said groove, of a bolt extending across saidgroove and provided with a transverse openlng therein, and a flexibleconnection fastened to one end of the sash cord and at the other end tosaid bolt, the latter attachment being made by passing the extremity ofsaid flexible connection through the opening in the bolt and windingseveral coils around said bolt.

4. The combination, with the lower sash having a groove in its edge, anda sash cord extending into said groove, of a bolt extend- Patented Aug.30, 1910.
